Frequently Asked Questions
How do I get an itemized medical bill?
You have the legal right to an itemized bill. Call the hospital billing department and request one specifically — the summary bill you receive by default doesn't show individual charges. Review each line item and CPT code.
What are CPT codes?
CPT (Current Procedural Terminology) codes are 5-digit numbers that identify every medical service. Each code has a Medicare-set price. If you're billed for a CPT code you don't recognize, look it up — you may have been charged for a service you didn't receive.
What is upcoding?
Upcoding is when a provider bills for a more expensive service than was actually performed. For example, billing a Level 5 ER visit when only a Level 3 was warranted. It's one of the most common billing errors and is worth disputing.
